摘要：

Tb3+-doped CaO-MgO-SiO2 glass ceramics have been prepared and characterized. The structure and optical properties of the glass ceramics were studied by XRD, SEM, Raman, and fluorescence spectra. The precipitated crystalline phase in the glass ceramics was columnar CaMgSi2O6. Raman spectra showed the introduction of rare earth nearly had no influence on the sample structure. Fluorescence measurements showed that Tb3+ ions entered into the diopside crystalline phase and induced a much stronger emission in the glass ceramics than that in the corresponding glass. With increase of Tb3+ content and the introduction of Gd3+, the fluorescence intensity of the luminescent glass ceramic increased. (c) 2008 Elsevier B.V. All rights reserved.
